K-theory provides a robust algebraic framework for classifying vector bundles and operator algebras, and it has emerged as an indispensable tool in the study of geometric phenomena such as positive ...

Graph polynomials serve as robust algebraic encodings of the intricate combinatorial properties inherent to graphs. At the heart of this discipline lies the Tutte polynomial, an invariant that not ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...
